What are visual signals that someone has AIDS?

Before we start, we should make a difference) between HIV and AIDS, so we can {talk about the symptoms. HIV (human immunodeficiency virus) infection happens when the virus gets into the body of human. It signifies that that person has the virus, that transports the virus, but that person is not positive. HIV infection, with no seeable symptoms and signs of sickness can last for years and stay unrecognised. AIDS (acquired immunodeficiency syndrome) is the final and most serious phase of HIV infection. In essence, it is a complete impairment of the defense (immune) function of the organism, and the person is open to different infections. We can recognize four stages of HIV infection:
- Acute HIV syndrome, followed by a latent period
- Growth of lymph nodes - a raising generalized lymphadenopathy
- AIDS-related complex (ARC)
- AIDS
Some time after a somebody has been infected with the HIV virus, close to 70% of them get signals of severe HIV syndrome. Symptoms last about 2 calendar weeks and they are similar to flu symptoms. Unluckily, nearly all of the infected do not discover them, but identification of these signals in this early stage would bring to better handling. Some signals are: fever, sore throat, rash, diarrhea, headache, loss of appetite, nausea...
After the initial reaction of the body, starts out latent period during which there is no visual aspect of any symptoms, except sometimes slenderly enlarged lymph nodes. HIV antibodies can be noticed by examination in the lab, but the virus is hard to trace in the blood. At this point, the patient is contagious, and he can transfer HIV to other people.
Following stage is growth of lymph nodes. This phase can be skipped over and patients can change instantly from latency point in the ARC phase.
The key signals of ARC are the temperature, long-term diarrhoea and weight loss along with some opportunistic infections, mouth candidiasis, vaginal candidiasis, herpes zoster, peripheral neuropathy, cervical dysplasia...
In The End, AIDS phase. The patient in this phase can recover from opportunistic infections, but they shortly re-occur, with critical and frequent symptoms. Healing of them all gets more and more hard and finally the patient dies. Results are viewable on the brain, bowels, junctions, kidneys, blood forming organs and skin. Common signals are present as in the ARC: temperature, diarrhea and loss of bodily mass. Weight loss is in particular pronounced and the patient in the ultimate phase looks like a real skeleton.
